Title: Wire twister guide arms - have structured dimensions to give low mass and reduce free flight wave of twisted wire
Inventor: WITTEK UWE DIPL ING
IPC: D07B7/02
Filed: 1989-12-27
Abstract: The wire guide arm at the twisting rotor of a double beat twisting machine, such as for mfg. steel cords, is dimensioned so that the ratio of its curve radius to height in each arm is 6:1 to 8:1. The ratio of the arm height to width is 1:3.5 to 1:4.5. ADVANTAGE - The two arms can be placed close together to minimise the free flight curve of the twisted material and give a low air resistance value. They have a low mass and therefore require less robust drive and braking systems.

Patent DE-3943469-A1 (DE)
Title: Non-marking RPM measurement at smooth shafts - determining angular deviation alpha of reflector of external resonator of laser-sensor compared to vertical of optical axis
Inventor: THIESSEN RAINER
IPC: G01P3/36
Filed: 1989-05-29
Abstract: The method for measuring the alternation in the length(L) of an external resonator uses a semi-conductor laser(HL), and the parallel beam falls on a reflector(R) which can be a single mirror. The reflector(R) is adjusted, so that it stands vertical to the optical axis of the system. A photo diode(PD) measures the intensity of the light produced by the laser. Its signal is evaluated by an evaluation unit(AE). The light intensity of the laser can also be measured with a beam divider (SL) and a photo diode(PDE), with a medium having a refractive index(n) filling a chamber(N). Whereby the light intensity of the laser with monotonic alternation of the value to be measured periodically varied, and from the num-ber of periods of the variation, the light intensity of the alternation of the value to be measured is determined. The indentification of the direction of alternation of the effect to be measured, results by the evaluation of the direction dependent signal shape of the occurring periodic variat-ions of the light intensity. USE/ADVANTAGE - System for marking rpm measurement at smooth shafts. Eliminates previous disadvantages and removes restriction in its use.

Title: Device for cleaning process water, esp. cooling water, using screen - comprises fixed inlet screen kept clean by suction head which traverses its upstream surface under effect of linear or rotational drives
Inventor: EIMER KLAUS DIPL ING
IPC: B01D29/01
Filed: 1990-03-13
Abstract: A process water screen with a suction device for removing deposited solid material from its upstream side is improved by providing a number of drive systems attached to the suction head or suction pipe. The vector sum of the motions caused by the drives defines the path in which the suction head traverses the surface of the screen. A telescopic section in the suction pipe and a double-acting linear drive enable the suction head to be moved towards or away from the screen. The suction pipe may be divided into pivoting sections by swivel joints. The suction pipe drive units may take the form of linear drives, so that the suction head moves in a path parallel or at right angles to the edges of the screen. USE/ADVANTAGE - This device is used in the filtering of process or cooling water, especially cooling water from rivers or lakes which is to be used e.g. in power station condensers. In the great majority of cooling water applications, the proposed filter screen cleaning method allows the cost of the system to be significantly reduced. The wear and other technical difficulties involved with moving band screens are eliminated, and the filter cleaning efficiency is greater than can be achieved in the case of filter screens cleaned by rakes.
